Is my battery bad or just not charging?
So I haven’t turned on my MacBook Air in a while and I was expecting to encounter SOME issues, so when it wouldn’t turn on at first, I wasn’t surprised.
It stayed that way when I plugged it in and I didn’t get any orange light to indicate on the MagSafe charger. I opened it up and took a look. Disconnected and reconnected everything and closed it back up. Tried resetting the SMC - nothing.
Then I plug it in and decide to just let it go for a while. “Maybe I’ll get lucky I think as I walk away.” And then I heard the chime.
I turn around and sure enough it’s turning on. But it says 1% then 0% once I’ve logged in. The battery isn’t charging, but the MagSafe is keeping the system on. That’s weird. So I check the battery and get this from CoconutBattery:
- Current Charge - 0 mAh
- Full Charge Capacity - 3101 mAh
- Design Capacity - 4680 mAh
- Cycle Count - 79 (!!!)
- macOS Battery Status - Poor
- Battery Temp - 21.8°
- Charging with - 0 Watts
- Power adapter - Connected
So it looks like it’s registering the MagSafe power adapter, but the adapter won’t charge the battery… But also the battery doesn’t seem “dead” because it shows that there’s a 3101 mAh capacity right now that it’s just not recharging.
Is it possible I disconnected something while I was in there and I just need to open it back up?
Based on everything I’m seeing it should be working, no?
